Aquaporins: Stimulation by Vitamins, Steroids and Sugar Alcohols
By: Bud Brewster, C&T magazine
Aquaporins are proteins that reside in the cellular membrane. In response to osmotic forces, they control the passage of specific materials into and out of the cell. As reported previously, one type of aquaporin in human skin is aquaporin-3 (AQP3). Four personal care companies have studied the world of biochemicals to discover AQP3 stimulators from three different sources: vitamins, steroids and sugar alcohols, which are described here.
